DEVICE FOR SUPPLYING WATER T0 AUTOMOBILE-RADIATORS.

To all whom it may concern:

Be it known that I, \NILLrAM WELS- HAUSEN, a citizen of the UnitedStates, residin at Allenhurst, in the county of Monmouth and State ofNew Jersey, have invented certain new and useful Improvements in Devicesfor Supplying Water to Automobile-Radiators, of which the following is aspecification.

This invention has as its object to provide a device for supplying waterto the radiators of automobile and similar engines and for maintaining aconstant water level within the radiator. As is well-known, drivers ofautomobiles vexperience inconvenience when the water in the radiatorboils away and in fact unless the radiator is frequently inspected andkept properly filled with water, serious damage is liable to result notonly to the radiator but also to the engine cylinders as they becomeoverheated and the cylinder walls are scored by the pistons.Therefore,-the invention contemplates the provision of a water reservoirwhich may be conveniently filled and which is located upon the dashofthe vehicle where a water gage upon the reservoir will bein plain viewof the driver, conducting water from this reservoir to a valve chamberfrom which its flow to the upper head of the radiator is controlledautomatically by means of a float actuated valve so that as the waterlevel lowers in the said water head of the radiator, the valve will beautomatically opened and water will be permitted to flow from thereservoir to the said water head.

Another object of the invention is to so construct the device that thesame may be readily and conveniently applied to any of the ordinarytypes of radiators nowin use without disarranging the parts of theradiator.

In the accompanying drawings:

sectional view through the float and valve chambers of the device.

-In the drawings the numeral 1 indicates ingeneral a radiator of theordinary construction and provided with the usual upthe rear side of theradiator at the top thereof in practically all types of radiators now 1nuse, although it will be understood that where the radiator is notprovided with such an extension, thepipe 3 may communicate with theupper water head through the rear side or wall thereof and the deviceembodying the present invention may be similarly rearranged.

The numeral 4 indicates a supporting bracket of any desired constructionwhich is secured in any suitable manner to the rear side of theextension of the water head 2 and it serves to support the body providedwith the float and valve chambers heretofore referred to. This body isindicated by the numeral 5 and may be of cast integral construction orbuilt up in any desired manner, and the same comprises. a substantiallycylindrical float chamber 6 and a smaller and substantially rectangularvalve chamber 7 which is located at the rear side of the wall of thefloat chamber and communicates with the interior of the said chamberthrough an opening 8 formed in that portion of the wall of the floatchamber which forms also a wall of the valve chamber 7. The chambers 6and 7 are preferably'open at their upper ends and a suitable cover plateor cap 9 is removably secured in place thereon for the purpose ofclosing the said chamber. A water supply pipe 10 leads from anyconvenient portion of the wall of the float chamber 6 and communicateswith the interior of the extension of the water head 2 of the radiatorand serves to conduct the water from the float chamber into the saidhead, and similarly provides for a corhorizontally disposed partition 11having a conical valve seat 12 formed therein, A

valve 13 of the needle type is arranged with-' in the valve chamber 7above the partition 11 and has a conical seating portion 14 normallyresting upon the seat 12 and closing the opening defined by this seat. Afloat 15 which is preferably cylindrical and of any desired constructionis arranged within the float chamber 6 and is of a diameter nearlyequalto the internal diameter of the said chamber so that while thefloat 15 may readily rise and fall with the level of the water in thesaid float chamber, it cannot have any considerable lateral play withinthechamber. A lever arm 16 is pivoted at its forward end as at 17 to theupper side of the float 15 and near itsother end this arm fits looselythrough an opening 18 formed in the wall which divides the float andvalve chambers at a point above the opening 8, the wall of the opening18 being preferably rounded longitudinally so as to afford a fuls crumfor the lever arm 16 and permit of free rocking of the arm. At thispoint it will be understood that when the float 15 lowers within thefloat chamber, the forward end of the arm 16 will move downwardly andthe arm will fulcrum upon the wall of the opening 18 thereby causing itsrear end to swing upwardly.- In order that this upward swing of the rearend of the arm 16 may serve to raise the valve 13 from its seat so as topermit water to flow from the lower portion of the valve chamber intothe upper portion thereof and thence into the float chamber, the saidrear end of the arm 16 is preferably forked as indicated by the numeral19 so as to straddle the shank of a screw 20 the head of which isindicated by the numeral 21 and is of such diameter as to be engaged bythe arms of the yoke 19 when the said rear end of the arm 18 is swungupwardly; The shank of the screw 20 is threaded and adjustably fittedinto a threaded bore 22 formed in the upper end of the valve 13 and,consequently, by rota tably adjusting the screw 20, the position of itshead 21 with relation to the yoke 19 of the arm 16 may be varied so thatthe valve may be caused to open automatically when a selectedpredetermined water level has been reached.

A pipe 23 communicates at its forward end with the lower portion of thevalve chamber 7 and this pipe leads from the bottom of the waterreservoir heretofore referred to and which reservoir is indicated by thenumeral 24 and is, as before stated, mounted upon the dashboard of thevehicle The waterglass for the reservoir is indicated by the numeral 25and is preferably located at the rear side of the reservoir so as to bein full view of the driver of the machine.

A suitable cut-off valve 26 is the pipe 23 immediately below thereservoir 24 so that if desired the flow of water from the reservoir maybe entirely out off, as for example when it is found necessary tocompletely drain the radiator and water jacket.

It will be understood that due to the maninterposed in 68 ner in whichthe arm 16 is fulcrumed through the dividing wall between the float andvalve chambers, the employment of troublesome pivotal connections isobviated and the removal of the valve or the float is rendered easy whenrequired. It will also .be apparent that the abutment screw 20 maycommunication between the chambers and with a second opening locatedabove the firstmentioned opening and having its wall roundedlongitudinally, and a lever arm connected with the float and operativelyengaged with the valve and at an intermediate point loosely fulcrumedthrough said opening, the float chamber having an outlet opening and thevalve chamber having an inlet opening and the latter being located belowthe valve. 2. A water supply device of the class described including afloat chamber, a valve chamber in communication therewith, a floatwithin the float chamber, a valve with in the valve chamber, a dividingwall between the chambers formed with an opening establish' ing'commnnication between the chambers and with a second opening locatedabove the first-mentioned opening and having its wall roundedlongitudinally, and a lever :lrm connected lvlvitili the1 floatandoperativ y engaged wit t e va ve and at an intermediate point looselyfulcrumed through said opening, the float chamber having an outletopening and the valve chamber having an inlet opening-and the latterbeing located below the valve, the said float being of a diameter nearlynal to the interior diameter of the float c amber.
